my 1gb transcend pen drive does not work properly

[sumangh01]

When i try to copy some files to my pen drive from my home computer, it shows an error. "use the chkdsk utility" but the files shows in the drive. and when i want to delete the file it shows another error.." the directory is not empty" if it is directory. for filr it deletes that file but when i refresh it, it shows the files again. And i have to format the drive..
please suggest what should i do.
i use symentac antivirus, spybot search & destroy, and comodo firewall.

where did you buy it and for how much?

that means to delete file you have to format to do so..?

I bought it about a years ago for Rs.640. But when i copy some file from my office computer it works fine.
may be it is affected by virus. but i dont know anything more about it.

Have you tried formatting the disk? I sometimes have faced the problem of corrupted files, and it usually gets solved after a format.

Format it in safe mode
